Family Limitation is a pamphlet written by American family planning activist, eugenicist, educator, writer, and nurse Margaret Sanger that was published in 1914. It was one of the first guides to birth control published in the United States. The 16-page pamphlet details information on, and ingredients for, various contraceptive methods and included illustrations and instructions for use. After the pamphlet was released, Sanger was forced to flee the United States to Britain to avoid prosecution under federal anti-obscenity laws, the Comstock Act, which prohibited disseminating information about contraception.
